Title: Improvements in or relating to Linkage Joints and the Production thereof
IPC: F16C11/06
Filed: 1966-09-21
Abstract: 1,167,752. Making pivots; dies. HEIM UNIVERSAL CORP. 21 Sept., 1966 [28 Sept., 1965], No. 42164/66. Headings B3A and B3H. [Also in Division E2] One member 1 of a linkage joint is made by punching a hole 13 in a sheet-metal member, placing the member over a die 14 and forcing the member into the die by a punch 17 whose pilot pin 20 is larger than the hole to smooth the edge of the hole by metal flow. The member is preferably cold-rolled strip steel. The pilot pin has a blunt point 24 and a bowl-shaped portion 21 which co-operates with the lower die 14 to shape the member. The dimensions of the pilot pin may be more than 20% greater than the dimensions of the hole, preferably 50%. The cross-section of the pin and the hole may be elliptical.

Title: Batch weighing
Inventor: BOADLE CAMPBELL DEAN
IPC: G01G13/00
Filed: 1962-11-08
Abstract: 986, 702. Weighing apparatus. GIRLING Ltd. Nov. 12, 1963 [Nov. 8, 1962], No. 42199/62. Headings G1N and G1W. Relates to an open topped weigh hopper which is supported on electrical load cells and inverted automatically by an electric motor to permit discharge thereof when a required load is attained. A hopper 9 (Fig.2) has a shaft 16 rotatable in bearings 8 carried by a frame 7 supported on a plurality of load cells 6a to 6c (Fig. 3). The output from the cells is summated and the resultant output signal is used to start a motor 12 which rotates the shaft 16 through a gear box 11 sprockets 13, 15 and chain 15. A micro switch 17 is engaged by a projection 18 on the sprocket 15 when the hopper has rotated 180 degrees whereby the motor is switched off. After discharge a further switch (not shown) starts the motor and the hopper is rotated a further 180 degrees to receive the next batch. The tare weight of the hopper and appendages is compensated for by a fixed signal superimposed on the cell output. Several different ingredients may be added in turn to the hopper the proportion of each being controlled by signals from the load cells and when the required final total weight is reached the motor is energized to invert the hopper. The hopper is surrounded by a casing 1 having a feed inlet 3 and discharge outlet 4. The hopper may be arranged to oscillate through 180 degrees or even through less than 180 degrees.

Title: Aircraft control system
IPC: G05D1/06
Filed: 1964-10-16
Abstract: 1,082,815. Automatic control of aircraft. SPERRY RAND CORPORATION. Oct. 16, 1964 [Oct. 23, 1963], No.42273/64. Heading G3R. In an aircraft control system, a control surface or prime mover is automatically controlled to maintain angle of attack equal to a desired value, the desired value and whether the control surface or prime mover is controlled, being determined automatically by which mode of operation of the aircraft is selected. As described, the angle of flight of an aircraft in a vertical plane is computed from signals dependent on airspeed and rate of change of altitude. A signal representing angle of attack is then obtained by subtracting a signal dependent on pitch attitude derived from a gyro vertical. The angle of attack signal is compensated for the effect of bank by a signal from the appropriate pick-off of the gyro-vertical and transmitted by a servomotor operated synchro and lowpass filter for comparison with a signal representing a desired angle of attack selected by a switch to suit the mode of operation of the aircraft e. g. take-off, go-around, approach or altitude hold. In the two first mentioned modes of operation any angle of attack error is automatically corrected by applying the error signal to a servomotor system operating the elevators. In the two last mentioned modes of operation any angle of attack error is automatically corrected by applying the error signal to a separate servomotor system operating the throttles of the aircraft engines. High frequency disturbances are detected by signals representing longitudinal acceleration of the aircraft computed from forward accelerometer signals and signals from the pitch pick-off of the gyro vertical. The signals so computed control the elevator or engine servomotor system, whichever is in operation, through a high-pass filter. To reduce the angle of attack during turbulent wind conditions so as to maintain a safe margin from stall, signals from an aerodynamic angle of attack detector are applied through a high-pass resistance-condenser network and a diode-rectifier arrangement so that increases of angle of attack above the average are applied to the appropriate aircraft servomotor control system in opposition to the signal representing desired angle of attack. Aircraft flaps may be manually controlled through a separate servomotor system in which case the desired angle of attack is automatically modified in dependence on flap angle through a modifier which is adjusted automatically in dependence on the mode of aircraft operation selected.

Abstract: 1,154,580. Photographic processing apparatus. PHOTOMATON G.C.S.A. Sept. 30, 1966 [Oct. 1, 1965; July 6, 1966], No.43879/66. Heading G2A. A photographic processing apparatus comprises a tank having side walls 1, and divided into compartments 4 by partitions 2. Each compartment has a pair of opposed slots 5 in the upper edges of the wall portions, for supporting the conveyer assemblies, one to each compartment. Each assembly is built up between a pair of side plates 13a, 13b, and consists of three sets of three rollers each. The rollers of each set are biased together by rubber bands 15. The uppermost central roller of each assembly is mounted on a shaft 8 fitting into H-shaped bearings 6a, 6b at each end. These bearings slide vertically into the slots 5, and so can readily be removed for cleaning, and replaced. Shaft 8 is also the driving shaft, and all the rollers in each assembly are driven from shaft 8 by a chain 19. One end of shaft 8 extends into a housing 22, where it engages, via a pair of bevel gears (23, 24, Fig. 5 not shown) with a motor-driven transmission which has inter-engaging dog-elements 26a, 26b. Thus when all the dog-elements are in engagement, the drive from the motor is transmitted to all the conveyer assemblies. When an assembly is to be removed, the inter-engaging parts of the dog-elements are oriented to a vertical position, so that the parts simply slide out of engagement as the assembly is lifted vertically out of the tank. The film strip being processed is passed down into one compartment and then up again, and is guided into the next compartment by a semicircular bridge (30, Fig. 6 not shown), where at the same time it can be briefly exposed to illumination from a lamp (35) and filter (36) as part of the processing. The processing apparatus can be part of a selfcontained photographic booth in which, in order to accommodate a lens system of longer focal length, the optical system of Fig. 8 (not shown) is used, which at the same time rectifies the image.

Title: Process for the manufacture of phloroglucinol
IPC: C07C37/05
Filed: 1961-12-07
Abstract: Phloroglucinol is made by hydrolysing 1:3:5 triamino-benzene obtained by the reduction of 5-nitro-1:3 diamino-benzene. Hydrolysis is effected in known manner with an aqueous mineral acid, preferably hydrochloric acid, at a temperature of 60 DEG  to 120 DEG  C. Reduction reaction may be effected with hydrogen under pressure in presence of a hydrogenation catalyst, e.g. platinum, palladium or nickel; or by using base metals, e.g. tin, zinc, aluminium or iron in the presence of a mineral acid or a lower aliphatic carboxylic acid, e.g. acetic acid or formic acid. Isolation of the 1:3:5 triamino-benzene as a solid trihydrochloride from the reduction mixture before hydrolysis is carried out produces phloroglucinol of high purity.  Two examples are given of the reduction of 5-nitro-1:3-diamino-benzene, one with hydrogen in the presence of nickel and the other with iron powder and 32% hydrochloric acid. Specification 1,003,785 is referred to.
